Metallics JBSC81 – Frequently Asked Questions

1) How many screws come in a pack of the Metallics JBSC81 8-32 button head socket screws?
The JBSC81 ships as a jar of 100, and 100 count is the order minimum. If you need a different size or a different pack count, Metallics does build the BSC series in other combinations by request.
2) Will these 8-32 screws thread into a standard 8-32 tapped hole in an electrical enclosure or device box?
Yes. The thread is 8-32 UN form at 32 threads per inch, made to ANSI/ASME B1.1, which is the standard Unified inch thread, so it mates with any 8-32 tapped hole or 8-32 nut. Usable length is 1 in.
3) Do these black alloy steel screws have any corrosion protection for outdoor or damp locations?
They are supplied plain. The black is the alloy steel's own black oxide-style finish, not a plated or coated corrosion barrier, so for wet, exterior, or washdown locations pick a stainless or hot-dip galvanized fastener instead.
4) What size hex key do I need to drive an 8-32 Metallics button head socket cap screw?
It is a socket head with a hex (internal allen) drive, not a slotted or Phillips screw, so you need a hex key rather than a screwdriver. The socket depth is 0.052 in., so a key with a short reach still engages fully. Head width runs 0.298 to 0.312 in. and head height 0.077 to 0.087 in., which is the low profile a button head gives you.
5) Do Metallics JBSC81 cap screws meet Buy American requirements on a government or institutional job?
Metallics lists the JBSC81 as both ARRA compliant and Buy American compliant. Country of origin is China, so if your specification demands domestic melt and manufacture rather than the ARRA/Buy American compliance designation, verify against the exact clause in your contract.
6) What dimensional standard are these button head socket screws made to, for spec submittal?
Head and body dimensions follow ASME B18.3-2012, the standard for socket cap screws, and threads follow ANSI/ASME B1.1. That pairing is what a submittal reviewer usually wants to see on an 8-32 socket screw. Note that on this series, Class 3A threads apply, with screws over 1 in. diameter falling to Class 2A.
7) Why is a button head screw used instead of a standard socket head cap screw?
Head height on the JBSC81 is only 0.077 to 0.087 in., with a 0.298 to 0.312 in. rounded head. That low, domed profile sits nearly flush and does not snag, which is why electricians and panel builders use it on cover plates, trim, and anywhere a tall cylindrical cap screw head would interfere. The tradeoff is less socket depth and lower strength duty than a full-height socket head cap screw.
8) Is a 1 inch long 8-32 screw subject to tensile testing?
Yes. Metallics notes that screws must be at least 3 diameters long to be tensile tested, and at 1 in. long on a 0.164 in. nominal 8-32 body this screw is well past that. Minimum tensile load is 1,940 lb.
9) How much does a jar of 100 Metallics JBSC81 screws weigh for shipping?
A jar of 100 weighs 0.53 lbs, with the jar itself measuring 3 x 3 x 2.15 in. Easy to add to a mixed MRO order without affecting freight.
